The Earth’s average temperature is gradually rising due to emissions of greenhouse gasses primarily attributed to human activities. This global warming has direct and signfiicant impacts to the polar ice caps, which are an essential part of the Earth’s climate and weather regulation systems. With glacial ice melting, an abundance of water is released, destabilizing oceanic and terrestrial ecosystems, rising sea levels and threatening the Arctic’s biodiversity.
Polar ice caps are unique, multi-dimensional and fragile natural phenomena. ice sheets, packed with a number of ice elements, are unstable and difficult to replace if diminished or damaged, with far-reaching effects. The Arctic in particular contains a significant portion of the Earth’s icy frozen mass and consists of vast ice deserts and glaciers, both being naturally melitng with season changes.
Yet, due to global warming, polar ice caps have been facing unprecedented melting rates. In the Antarctic, for example, some 200 billion tons of ice are currently being lost each year, resulting in sea-level rises, destabilizing coastlines and intensifying natural disasters. In the Arctic, new record lows in sea ice have been observed in both summers and winters since the 1980s, a 20% reduction overall since 1979. With this, ice-dependent species are threatened by habitat and food loss, while local communities and artistic livelihoods that rely on healthy oceans are disrupted.
The permafrost in Northern latitudes include ground, lake and river ice, as well as frozen soil, designated as a ‘’thermal boundary’’, where temperatures remain. below freezing, yet their regulation of temperatures is severely impacted by climate change and higher temperatures, resulting in the release of over a trillion tons of carbon dioxide to the atmosphere and serving to accelerate the process of global warming.
A number of human activities contribute to this warming, from the utilization of fossil fuels to agriculture, with the burning of coal as the main release of CO2 in the atmosphere. As additional heat is released into the atmosphere, the polar regions are affected more than ever, with decreased sea-ice cover and even more extreme weather events, such as prolonged periods of drought and heat waves.
In summary, not only does global warming accelerate the melting of polar ice caps, but its resulting extreme weather conditions affect the climate in other regions, having drastic effects on human life and ecosystems. It is therefore of utmost importance to reduce emissions, with increased investment in green energy, sustainability projects, and efficient transportation systems. We must act now, to protect polar ice caps and preserve them for future generations.
